I play association football since a very young age. Now I notice that when I stand my knees don't really touch each other, which seems to be a typical symptom of bow legs (Genu Varum). Also, I'm a right-footed player, and I notice that now I tend to walk on the outside of my right foot/walk with my right foot pointing outwards with an angle larger than that of my left foot. When I watch football matches, I notice that this situation seems to be even more extreme in some professional players, i.e. when they're lying naturally on the ground they have their playing foot pointing outward much more than the other foot.
Has there been any study/research on this topic? Because when I search the web I find surprisingly little information on it. I suspect maybe my bow legs also have a genetic component to it but I'm not sure how much my football activities have had an influence on it. If it's true that football exacerbates bow legs, should I stop playing football? Or is there some other advice to alleviate the situation.
